摘要：

Two new scandium platinum silicides, ScPt2Si (orthorhombic, Cmcm, a = 3.6653(6) angstrom, b = 9.831(1) angstrom, c = 6.967(1) angstrom, Z = 4) and Sc5Pt9Si7 (hexagonal, P (6) over bar, a = 9.9418(5) angstrom, c = 3.8832(2) angstrom, Z = 1) were prepared by reaction of the elements in an electric arc furnace and subsequent annealing. The crystal structures were solved and refined from single crystal diffraction data. ScPt2Si crystallizes with an 'inverse' MgCuAl2 structure whereas Sc5Pt9Si7 forms a variant of the Zr2Fe12P7 type.
